To all whom it 'maffj concern:

Bo it known the-t i, ARTHUR Hoe/e333 Lovnaov, e, citizen ci the United StetesV and eiesident of Red Bank, in the county oi Monmouth end State of New Jersey;V have invent-eil a new and Improved'ir-Heeter, oi which the following is a full, clem, and exec-t desoription.

The invention relates te heaters for heet ing buildings and its object is to provide e new and improved en heater made in sec# tions each of Wliicli is peeticallv e complete air 'heater in itself, thus permitting ofeonvenientlv setting up any desired nuinbe oi sections one along side the other, iiceording to the heating capacity required of the heater. `A

A further object of the invention is piovitle a perfect combustion of theiuel end to heet and circulate the aii in such e. menne? that the burning fuel is utilized to the 'fullest advantage.

The invention consists of novel feature-s and parts end combinations of the which will be moreiully deseioeci hereinaf- A practical embodiment of the invention is represented in the accompanying drawings forming e port of this specioetien in which similar characters of reeienee indicate conre- Sponding parts in ell the views. 4

The air heater in its geneiel eonstmction consists of a front section. A, end se tion B end oneoi e pluielit5Y intezniei: .te sections C interlposed between the sections e. and B, as pleinijv iilustieted in. the ei' .iviY1 es A {fry} the several sections A, B and C be gri-'mstenectogether by boite or otiiei "ne ius- Lening devices, to peniit oi convenlentljvv iiicieasing or decfeasing the nunibe et ii mediate sections according 'to the "meeting capacity jec'uired by the en" heater.

Een een lies i povicico. et the une vesely extending nos F p lOt erases closed and a corresponding valve L is opened then air circulates through the corresponding air heating chamber G by passing through the open valve L into the chamber N, thus preventing dorniancyv in the air chamber G, the register for which has been closed. The air escapes from the chamber N by opening anothervalve L corresponding to a register that is open.

From the foregoing it will be seen that practically each section of the heater contains a portion oi the i'ire box, grate, asl: pit, air chambers and smoke chambers, to per mit olE using more or less intermediate sec tions C, according to the heating capacity required olA `the heater. lt will also be noticed that by the arrangements described it is not necessary to remove any or" the pipes in case new intermediate sections C are to be added. or intermediate sections are removed therefrom, that is, the pipe arrangement to the different rooms can be left undisturbed when increasing or reducing the sii/ie oi the heater. lt will further be noticed that in each section, the air to be warmed or heated enters at the bottom and cannot escape at any other point except the outlet nipples G at the sides oi" the heater near the top thereof.

ily l'orming the side walls of the lire box l) by the air heating chambers G, and by spac- `-ing the sides thereol, 1t is evident that the heat arising from the burning fuel in the rire box l) quickly and highlT heats the air passing through the said chamber G. i

ily reference to Figs. 4, 5 and it will be seen that the sides and inner rounded ofi ends olz each heating chamber G are integral and thus present no joints to 'the heat and smoke ol' the burning hiel in the fire box 5 that is, the chambers G project into the iire without one touching the other, and are thus capable ol ready expansion and contraction, thereby insuring long liie to the heater besides permitting removal of ail intermediate section whenever it is desired to do so. It will also be noticed that the air passing through the fresh nir chambers J is thoroughly heated before it reaches the corner nipples G4 at the front section A and rear end section B, as

this additional air has to travel a long dis-. tance over the heated outer walls of the srhoke chambers H and H.
